Re: Project: Trigger GPIO via SDR Received Signal

You could modify the python output of a gnuradio flow graph to use the gpio library. You'd just have to figure out the right place to put lines of code similar to this: gpio_error = None try: import RPi.GPIO as GPIO GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) control_pins = (16,) GPIO.setup(con...

Re: KerberosSDR Developments in 2020

These switches you've used here look like an elegant solution to the programmatic disconnect-reconnect for syncing the kerberos. Sounds like it worked successfully which is great. Can you advise the part that you've used for the switch? Is this fork the same software you've used to control the abov...

Re: HackRf Woes

It sounds like you're trying to dive straight into the deep end without even testing the waters first. I can assure you that Pentoo has gnuradio installed, but going straight for Pentoo isn't the best idea. If you're looking for a more user friendly OS with some pre-built SDR tools check out DragonO...

Re: Still can't get KSDR working (Raspberry Pi 4)

That image should support everything the standard Raspbian image supports. Everything you're describing there sounds like a power issue with the pi itself.

Re: Still can't get KSDR working (Raspberry Pi 4)

Are you providing external power to the KSDR?

Re: Battery powered pi + Kerberos setup - shutting down the pi?

I'm not aware of SSH being disabled, but if it is. it's easy enough to enable with raspi-config. The VNC Viewer client for android works pretty well on a tablet as well.
Personally I always just pull the plug. I don't run into problems that way, but it doesn't make it right.

Re: Linux PC -- No supported device found. WTF?

Hello, I am running into this same problem and running it through a hub doesn't help. Can you post some of the text from dmesg when this is running properly, such as the idVendor? I still don't know what to look for in dmesg if the Kerberos SDR is running properly. Certainly, the rtl_test isn't wor...

Re: DOA on Intermittent Signals

I'm also curious what the status of the new software is. I've been holding off making significant changes to the current software since the new software is coming out soon.
